good day my friends

I have an E Manage blue with Ignition and injection harnesses + the standard harness that comes with it .

how can the extra harnesses ( Ignition and injection ) help in tuning my turbo max along with the standard harness ?

The ignition harness allows you retard timing/spark through the ignition map, the injector harness allows you to add duty cycle through the additional injector map.

Ignition is negative values only

Injector is positive only. I think you can put in negative values but my wideband is broken so I can't confirm if negative does anything but I think you can only add fuel with the injector harness.

You can use the greddy pressure sensor reading to adjust the values of timing retard and additional injection. For example there is no psi reading on the emanage blue but kpa converts to psi so if you wanted to pull 1 degree of timing at 7.25 psi it would be 50 kpa.

You can add and subtract fuel via injectors.

Ok and what will I gain from that ? I think that will expand fuel map .

Increase fuel without messing with maf voltage and timing.

If you increase fuel on airflow adjustment map it can add timing, with the harness you can add (or take away?) without the timing changing on the additional injection map.
